s14 tension rod problem?

[missionsix010]

ok so here is the problem......
the car befor i put the tension rods would shake between 60 and 80 but it was very little and maybe a little bit more when i got off the gas but it was never a big deal. i brought it to a shop months ago for a differnt problem and they said i needed tension rods.

so a few days ago got new tension rods(isis) matched them up the best i could be for putting them in. after putting them in at like 60 you can feel it start pulling to the right alittle and shaking and any thing over 65 the car shakes so much it might fall apart.any ideas???

in the morning it was driving fine with a very little shake(stock tension rods) that went away with increased speed then 4 hours later(w/new isis tension rods) cant even go over 65 with out feeling like the car is going to shake apart
